| titleOfInvention | Method and apparatus for detecting slack face of shield machine |
| abstract | The present invention provides a method and an apparatus for detecting a slack face of a shield machine that can detect the presence of a slack that induces a collapse, not a detection of a collapse, and can call attention at the stage before the collapse. A soil wet density detecting means and a soil wet density and moisture density (water content) detecting means are provided at the front part of the shield machine, and the soil wet density and moisture density (water content) are grasped. Predict the fall of natural ground. The soil wet density detecting means and the moisture density (water content) detecting means are provided with a source rod to emit gamma rays and neutron rays from the front of the shield machine, and the gamma rays and neutron rays emitted from the source rod are Scattering is repeated in the course of traveling inside, and the wet density and water content are determined from the amount of radiation reaching the detector.
